“…These regulations have laid down the application of "minimum requirements to the energy performance of building elements that form part of the building envelope and that have a significant impact on the energy performance of the building envelope when they are retrofitted or replaced". However, it is important to highlight the existence of different transpositions of the EPBD for each European country (EU-28 and Norway), which means that there are different regulations but with the common objective of achieving a Nearly Zero-Energy Building (NZEB) able to combine both comfort and minimum energy consumption [4].…”

Building envelopes are the part of the buildings most exposed to the inclement weather and thus have significant impact on the energy performance as a consequence of higher thermal transfers produced. Therefore, new solutions for building envelopes are required as a way to save energy in residential buildings. In this regard, the European Directives 2002/91/EC and 2010/31/EU on Energy Performance of Buildings (EPBD) have laid down the application of minimum requirements to the energy performance of building elements that form part of the envelope. Designers require, in the early stages, a method to obtain information about the energy performance of the building, as design decisions made at this stage might compromise the performance of the final design. Among the possible energy-savings solutions the most effective are not only those related to the construction design but also those that consider constructive materials with low thermal transmittance. Consequently, the objective of this study is to analyze and compare, by means of energy simulations, different constructive solutions applied to the building envelopes in terms of construction design and constructive materials. The results obtained showed that the energy demand and CO2 emissions of residential buildings can be reduced by 60% and 95% respectively when constructive solutions with low U-values are implemented. These reductions make also possible the enhancement of the energy rating of the buildings.

“…The cooling and heating demand are used to define the Energy Performance Certificates (EPCs). The EPCs calculation method is very similar in all countries, using the annual energy demand of the building to calculate the energy rating [16]. For such calculation, it is necessary to be very precise defining the building envelope, materials, thermal bridges, heating and cooling, etc.…”

Applying Renewable Energy Technologies in an Integrated Optimization Method for Residential Building’s Design

Designing a Zero Energy Building (ZEB) requires an optimal choice of the materials of a building envelope. Different material properties and window areas could be selected to generate a set of possibilities of the design of a building, being the demand defined by its thermal characteristics. The energy demand of a building could be produced with renewable systems such as photovoltaic. Moreover, the HVAC (Heating, Ventilation, and Air Conditioning) systems could be selected considering the system cost. The present methodology focuses on finding a balance between investment and low energy consumption for a building, based on an integrated optimization method. Such methodology applies a Tabu search algorithm and a simplified model to select the passive design. Afterwards, active elements of the design, as photovoltaic systems, are selected. Therefore, the methodology faces the problem of estimating the annual energy demand and the life cycle cost. The goal is the design of a building with a large amount of energy generated by renewable energy, to have a ZEB, and in the worst case, a nearly Zero Energy Building (nZEB). This methodology reduces investment, reduces the energy demand and selects the best construction materials, renewable energy, and air conditioning system. The present paper analyzes a set of case studies considering different climatic zones in Spain. The results conclude that the methodology could help builders in the design stage, to find a new design that allows a ZEB with the optimal life cycle cost.The present paper explores a methodology to design a nZEB building, by choosing design elements in two steps (Figure 1). Firstly, the selection of passive elements, and secondly the selection of active elements with a system of photovoltaic panels to generate the energy required by such building. To achieve a ZEB (Zero Energy Building), the Building Integrated Photovoltaic (BIPV) systems used to generate electricity can play an important role [2]. A comprehensive review of the current state of the art in the area of the BIPV technology is shown in [3]. Moreover, some studies have verified the validity of BIPV systems for the challenge of Zero Energy Buildings [4]. Appl. Sci. 2018, 8, x FOR PEER REVIEW 2 of 14 remaining energy needs and renewable energies. Therefore, a nZEB will not only imply an optimized design and construction, but also the exploitation of energy resources in the most efficient way.

“…The correct definition of climatic zones for building construction allows building materials to be adequately selected for different geographic regions, thus minimizing energy costs for heating and cooling (Carpio et al, 2014(Carpio et al, , 2015. Chile is the longest country in the world from north to south and is characterized by the presence of multiple climatic zones (from tropical climates in the north to the Antarctic in the far south) (Kottek et al, 2006).…”

Abstract. This paper presents the results of the updated boundaries of thermal zones in the tree southern regions of Chile, based on the method of heating degrees-days according to hourly temperature measurements at meteorological stations in the last decade. The Ministry of Housing and Urban Planning of Chile has not updated these boundaries since 1999. Using the Climatic Severity index method, the relative energy consumption of dwellings was analyzed for cooling and heating in summer and winter periods, respectively. The analysis revealed that, within the limits of a single thermal zone, the energy costs for cooling in the summer period of the same house may differ by 50 %.
